The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0037] See also Figure 1 , Figure 3 and Figure 4 The present application provides a tool holder 100 for storing a tool 200 , which includes a tool holder body 10 , a travel member 20 and at least two clamping members 30 , wherein the travel member 20 and all the clamping members 30 are connected to the tool holder body 10 .

[0038] Please also refer to Figure 5 and Figure 6 The stroke member 20 includes a stroke portion 21, and the stroke portion 21 has different initial positions and first positions relative to the tool holder body 10, and the initial position and the first position are spaced apart along the first direction. The stroke portion 21 slides between the initial position and the first position relative to the tool holder body 10. All clamping members 30 are located on the same side of the stroke member 20, and all clamping members 30 are arranged on opposite sides of the tool 200 along a second direction intersecting with the first direction. Among them, the tool 200 contacts the stroke portion 21 along the first direction and pushes the stroke portion 21 to slide from the initial position to the first position, and when the stroke portion 21 is located at the first position, the clamping members 30 located on both sides of the tool 200 are controlled to slide along the second direction to clamp the tool 200.

[0039] Specifically, when the tool 200 is not in contact with the stroke portion 21, the stroke portion 21 is located at the initial position. When the tool 200 slides along the first direction and contacts the stroke portion 21, thereby driving the stroke portion 21 to slide along the first direction and slide from the initial position to the first position, the clamping members 30 located on both sides of the tool 200 are controlled to slide along the second direction to clamp the tool 200 to fix the tool 200. In this way, it is helpful to improve the reliability of the connection between the tool 200 and the tool holder 100, so as to prevent the tool 200 from falling off the tool holder 100, thereby making the tool holder 100 have higher safety.

[0040] In addition, it is worth mentioning that, since all the clamping members are arranged at intervals on both sides of the tool 200, each pair of two clamping members that are opposite and arranged at intervals along the second direction can also define a guide channel for guiding the tool 200 to slide, thereby making the sliding of the tool 200 more stable. Therefore, the tool 200 does not deviate during the sliding process, so it can accurately contact the travel portion 21 and drive the travel portion 21 to slide.

[0041] Specifically, the clamping members 30 may be two, three, or more. Preferably, the clamping members 30 are arranged in pairs, and all pairs of the clamping members 30 are arranged at intervals or continuously along the first direction. Alternatively, all pairs of the clamping members 30 may also be arranged at intervals or continuously along a fourth direction intersecting both the first direction and the second direction. The two clamping members 30 in each pair of clamping members 30 are arranged at intervals on both sides of the tool 200 along the second direction. Preferably, the clamping members 30 are a pair, which helps to reduce the use of parts of the tool holder 100, thereby making the assembly of the tool holder 100 simpler.

[0042] Please refer again Figure 1 Preferably, the first direction coincides with the direction of gravity (e.g. Figure 1 Therefore, the tool 200 can slide downward under its own weight and abut against the travel portion 21. Figure 1 The fourth direction (as shown by arrow b) and Figure 1 The second direction is the thickness direction of the tool holder 100, and the fourth direction is the width direction of the tool holder 100.

[0043] Please refer again Figure 3 , Figure 4 and Figure 6 , wherein the travel portion 21 also has a second position relative to the tool holder body 10, and the first position and the second position are spaced apart along the first direction. When the travel portion 21 slides from the first position to the second position along the first direction under the action of the tool 200, the clamping members 30 located on both sides of the tool 200 are controlled to slide along the second direction and release the tool 200. In other words, when the travel portion 21 located at the first position continues to slide down to the second position under the action of the tool 200, all the clamping members are controlled to release the tool 200, so that all the clamping members can be separated from the tool 200, thereby facilitating the removal of the tool 200. It can be seen that the tool holder 100 provided in the present application also has a better removal convenience.

[0044] It can be understood that when all the clamping members clamp the tool 200, the tool 200 has its own downward gravity and is also subject to the static friction force applied to it by all the clamping members. The gravity and the sum of the static friction forces applied to the tool 200 by all the clamping members are in balance with each other. When the tool 200 needs to be taken out, the user needs to overcome the sum of all the static friction forces to do work. Therefore, the user applies a force greater than the sum of all the static friction forces to the tool 200 along the first direction, which can drive the tool 200 to drive the travel portion 21 to slide down from the first position to the second position. When the travel portion 21 slides to the second position, the clamping members 30 located on both sides of the tool 200 are controlled to slide along the second direction and release the tool 200. After the tool 200 is taken out, the travel portion 21 moves along a third direction (such as Figure 1 The mobile phone slides from the first position to the initial position (as shown by the arrow d) for the convenience of next use.

[0045] It is worth mentioning that, when the travel portion 21 slides from the initial position to the first position, and when the travel portion 21 slides from the second position to the initial position via the first position, the clamping portions 33 on both sides of the tool 200 release the tool 200. When the travel portion 21 slides from the first position to the second position, the clamping members 30 on both sides of the tool 200 clamp the tool 200.

[0046] Furthermore, the stroke member 20 further includes a stroke body 23 and a reset portion (not shown), the stroke body 23 is coupled to the tool holder body 10, and the reset portion is connected between the stroke body 23 and the stroke portion 21. The reset portion is used to provide a reset force that drives the stroke portion 21 to slide from the second position to the initial position along a third direction opposite to the first direction. Under the action of the reset portion, when the tool 200 is separated from the stroke portion 21, the stroke portion 21 located at the second position can be automatically reset to the initial position via the first position under the action of the reset portion, thereby avoiding manual operation, making the tool 200 easy to use.

[0047] Preferably, the reset portion may be a reset spring, and the reset spring is simple and easy to operate to automatically reset the travel portion 21.

[0048] Of course, the reset method of the travel portion 21 is not limited to the above-mentioned one. In some other embodiments, the reset portion can also be reset by being driven by a telescopic rod, a telescopic cylinder or other telescopic parts.

[0049] See also Figure 4In one embodiment, each clamping member 30 includes a driving portion 31 and a clamping portion 33 connected to the driving portion 31 in a transmission manner. When the travel portion 21 slides from the initial position to the first position, each driving portion 31 is controlled to extend along the second direction and drives the clamping portion 33 connected thereto to slide along the second direction to clamp the tool 200. Specifically, the driving portion 31 may be a telescopic cylinder, an electric strut, etc. When the travel portion 21 slides from the initial position to the first position along the first direction, each driving portion 31 extends along the second direction, and the clamping portion connected to each driving portion 31 can slide toward the tool 200 along the second direction to abut against the tool 200, so that the tool 200 can be clamped. When the travel portion 21 slides from the first position to the second position along the first direction, each driving portion 31 is controlled to contract along the second direction, and the clamping portion connected to each driving portion 31 can slide away from the tool 200 along the second direction and separate from the tool 200, so that the tool 200 can be released. Since the straight line between two points is the shortest, under the action of each driving part 31 , all the clamping parts 33 cooperate to quickly clamp or release the tool 200 .

[0050] Furthermore, each driving part 31 is connected to the stroke part 21 by signal. When the stroke part 21 slides from the initial position to the first position, the stroke part 21 sends a first control signal to each driving part 31. The first control signal is used to control the extension of each driving part 31. The first control signal can reduce the setting of the internal detection parts and controllers of the tool holder 100 on the one hand, and can also enable each driving part 31 to respond to the first control signal sent by the stroke part 21 in time, so that the clamping parts 33 located on both sides of the tool 200 can quickly clamp the tool 200.

[0051] It is worth mentioning that when the travel part 21 slides from the first position to the second position, the travel part 21 also sends a second control signal to each driving part 31, and the second control signal is used to control the contraction of each driving part 31 so that all clamping parts can release the tool 200, thereby facilitating the removal of the tool 200.

[0052] Of course, the starting method of each driving part 31 is not limited to the above one. In some other embodiments, the travel part 21 can also be a simple mechanical structure, and a position detection part and a controller are also provided in the tool holder 100, and the controller is electrically connected to the detection part and each driving part 31. The detection part is used to detect the current position of the travel part 21 and send it to the controller, and the controller is used to control that when the current position coincides with the first position, the driving part 31 is extended until all the clamping parts clamp the tool 200. The controller is also used to drive all the contractions when the current position coincides with the second position, so that the tool 200 can be separated from all the clamping parts.

[0053] It is worth mentioning that after all the clamping parts are separated from the tool 200, each driving part 31 continues to contract so that the distance between the two clamping parts in each pair of two clamping members opposite and spaced apart along the second direction increases, thereby facilitating the next insertion of the tool 200 between the clamping parts on both sides.

[0054] Each clamping member 30 further includes a separating portion 35. In the same clamping member 30, the separating portion 35 is connected between the tool holder body 10 and the clamping portion 33. The separating portion 35 is used to provide a separating force to drive the clamping portion 33 to separate from the tool 200. Therefore, when the travel portion 21 slides to the second position, in the same clamping member 30, the clamping portion 33 can also be separated from the tool 200 under the action of the separating portion 35. Therefore, even if the driving portion 31 fails or the speed of the driving portion 31 contraction is slow, it can still be ensured that the clamping portion 33 can be quickly separated from the tool 200, so that the tool holder 100 has better working reliability.

[0055] Preferably, the separation portion 35 is an elastic portion and extends along the second direction. Therefore, in the same clamping member 30, the direction of the separation force is the same as the direction of the driving portion 31 when it is extended and retracted, thereby further improving the reliability of the separation of the clamping portion 33 and the tool 200. Specifically, when all the clamping members 30 cooperate and clamp the tool 200, each separation portion 35 is in a stretched state. When each pair of two clamping portions 33 that are opposite and spaced apart along the second direction have the longest distance between them, each separation portion 35 is in a naturally straightened state or a stretched state.

[0056] The tool holder body 10 includes a body 11 and at least two limiting parts 13 connected to the body 11. The tool holder 100 also includes at least two limiting members 40 connected to the body 11. All limiting parts 13 and all limiting members 40 correspond to all clamping parts 33 one by one. The limiting parts 13 and limiting members 40 corresponding to the same clamping part 33 are arranged at intervals on the opposite sides of the clamping part 33 along the first direction, and clamp the clamping part 33. Therefore, under the action of all limiting parts 13 and all limiting members 40, each clamping part 33 can be prevented from sliding along the first direction, thereby helping to improve the stability of each clamping part 33 sliding along the second direction. In this way, all clamping members 30 can quickly clamp or release the tool 200.

[0057] Furthermore, each clamping member 30 is also provided with a positioning portion 37 connected to the clamping portion 33 therein, and each limiting member 40 has a first end and a second end arranged opposite to each other, and the first end of each limiting member 40 is sleeved on the corresponding positioning portion 37. The tool holder body 10 also includes at least two assembly portions 15, all assembly portions 15 correspond to all positioning portions 37 one by one, each assembly portion 15 is matched to the body 11 and is arranged at intervals with the corresponding positioning portion 37 in the first direction, and the second end of each limiting member 40 is sleeved on the corresponding assembly portion 15. Preferably, each limiting member 40 has a positioning portion 37, and the tool holder body 10 also includes at least two assembly portions 15, the first end of each limiting member 40 is sleeved on the corresponding positioning portion 37, and the second end of each limiting member 40 is sleeved on the corresponding assembly portion 15. Under the action of the positioning portion 37 and the assembly portion 15 , each clamping portion 33 can be stably limited between the corresponding positioning portion 37 and the assembly portion 15 along the second direction, so that the sliding of the clamping portion 33 is more stable.

[0058] Optionally, the assembly portion 15 and the positioning portion 37 corresponding to the same clamping portion are both extended and connected along the first direction, or the assembly portion 15 and the positioning portion 37 corresponding to the same clamping portion may also be spaced apart along the first direction.

[0059] Preferably, the limiter 40 is a compression spring. On the one hand, the elastic force applied to the corresponding clamping portion 33 by the compression spring after compression can make the clamping portion 33 abut against the corresponding assembly portion 15, so that the sliding of the clamping portion 33 is more stable; on the other hand, the compression spring also has better flexibility, so the clamping portion 33 has a certain buffer distance in the second direction. In the process of the clamping portion 33 sliding along the second direction, the compression spring moves synchronously with the clamping portion 33 through its own torsion. In other words, in the process of the clamping portion 33 sliding along the second direction, the compression spring always remains relatively still with the clamping portion 33. In this way, not only can the wear caused by the sliding of the clamping portion 33 relative to the compression spring be prevented, but also the resistance of the clamping portion 33 in the process of sliding along the second direction can be reduced, and the compression spring always has a larger contact area with the clamping portion 33.

[0060] See also Figure 2 , and refer again Figure 1 and Figure 3In some embodiments, the tool holder body 10 has a receiving cavity 112, a loading and unloading port 114 communicating with the receiving cavity 112 is provided on the tool holder body 10, and the travel member 20 and all the clamping members 30 are located in the receiving cavity 112. Specifically, the body 11 in the tool holder body 10 has a receiving cavity 112, a loading and unloading port 114 communicating with the receiving cavity 112 is provided on the body 11, and the travel member 20 and all the clamping members 30 are located in the receiving cavity 112. When the tool 200 needs to be stored, the tool 200 extends into the receiving cavity 112 along the first direction through the loading and unloading port 114 and abuts against the travel portion 21 to drive the travel portion 21 to slide. In the process of the travel portion 21 sliding from the initial position to the second position through the first position in sequence, the length of the tool 200 extending into the receiving cavity 112 increases. When the travel portion 21 slides to the second position, the tool 200 has the maximum length extending into the receiving cavity 112. By providing the receiving chamber 112, on the one hand, the aesthetics of the tool holder 100 can be improved, and on the other hand, the outside world can be prevented from interfering with the operation of the travel portion 21 and the clamping member 30, so that the tool holder 100 has better working reliability. In addition, since the tool 200 is stored in the receiving chamber 112, it can also prevent the blade of the tool 200 from cutting the user when the tool holder 100 falls.

[0061] In the tool holder 100, the tool 200 contacts the stroke portion 21 along the first direction and pushes the stroke portion 21 to slide from the initial position to the first position, and when the stroke portion 21 is at the first position, the clamping members 30 located on both sides of the tool 200 are controlled to slide along the second direction to clamp the tool 200. In this way, the reliability of the connection between the tool 200 and the tool holder 100 can be effectively improved, thereby preventing the tool 200 from falling off the tool holder 100. Therefore, the tool holder 100 provided in the present application has high safety.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
