[0039] A passage 401 is formed on the fixing disc 4, the cross section of the passage 401 is U-shaped, the inner end of the passage 401 communicates with the hollow part of the middle part of the fixing disc 4, and the outer side of the fixing disc 4 is detachably provided with a ring sleeve 6, and the side wall of the ring sleeve 6 is provided with an inlet and outlet hole 601 communicating with the passage 401 and used for introducing the bolt into the passage 401 or leading the bolt out of the passage 401.

[0040] As shown in Figure 3 , 11 In order to fix the ring sleeve 6 on the fixing disc 4, specifically, the side wall of the ring sleeve 6 is fixed with a lock column 15, the side wall of the fixing disc 4 is provided with a lock hole 16 for inserting the lock column 15, the inside of the fixing disc 4 is slidably connected with a lock block 18 through a fourth spring 17, and the side wall of the lock column 15 is provided with a lock groove 1501 for clamping the lock block 18, as shown in Figure 11 The sliding direction of the lock block 18 is perpendicular to the sliding direction of the lock column 15 inserted into the lock hole 17, and the end of the lock block 18 inserted into the lock groove 1501 is hemispherical, so that when the ring sleeve 6 is fixed on the fixing disc 4, the lock block 18 can be separated from the lock groove 1501 under the condition of pulling the ring sleeve 6, the ring sleeve 6 can be taken off, and after the lock column 15 is inserted into the inside of the lock hole 16, the ring sleeve 6 can be positioned, and the inlet and outlet hole 601 and the passage 401 can be kept in the state of alignment.

[0041] Specifically, the clamping part 3 includes a clamp sleeve 301 and a locking screw 302, the clamp sleeve 301 is fixed at one end of the inner sleeve 2, one side of the clamp sleeve 301 is provided with an opening, and the locking screw 302 is engaged on the opening, so that the size of the opening can be controlled by rotating the locking screw 302, the size of the inner cavity of the clamp sleeve 301 can be changed after the deformation of the clamp sleeve 301, and the clamping operation of the clamp sleeve 301 on the front end of the electric screwdriver can be realized.

[0042] Example two

[0043] As shown in Figures 1-12As shown, based on Embodiment 1, in order to automatically replenish the bolts into the channel 401 and quickly complete the bolt installation operation, this embodiment specifically provides a bolt storage component on the ring sleeve 6. The storage component includes a storage sleeve 8, which is rotatably sleeved on the ring sleeve 6. The storage sleeve 8 has multiple storage compartments 801 arranged in a ring shape inside. When the storage sleeve 8 is rotated, the multiple storage compartments 801 are alternately connected to the channel 401 through the inlet and outlet holes 601.

[0044] The interior of each storage compartment 801 is slidably connected by a second spring 9 to a pressure plate 10 for pressing the bolt toward the center of the ring 6. When the storage compartment 801 rotates to communicate with the channel 401, the pressure plate 10 presses the bolt into the interior of the channel 401.

[0045] To facilitate the insertion of bolts into the storage compartment 801, the bottom of the storage compartment 801 is open, and the lower end of the pressure plate 10 is inclined to the side away from the axis of the storage sleeve 8. When inserting bolts into the storage compartment 801, the bolts are pressed into the space between the pressure plate 10 and the ring sleeve 6 from the bottom of the storage compartment 801. At this time, the bolts squeeze the pressure plate 10, causing the pressure plate 10 to compress the second spring 9 and slide. The bolts are clamped between the pressure plate 10 and the ring sleeve 6 by the elastic pressure of the second spring 9.

[0046] After each storage compartment 801 has a bolt placed in it, the ring 6 and the storage sleeve 8 are installed on the fixing plate 4. After installation, the ring 6 and the fixing plate 4 are fixed relative to each other, and the inlet / outlet hole 601 is connected to the channel 401 (one storage compartment 801 is reserved without a bolt; during installation, this storage compartment 801 is aligned with the inlet / outlet hole 601 to prevent the bolt from accidentally entering the channel 401 during installation). The storage sleeve 8 can rotate relative to the ring 6 and the fixing plate 4. After rotating the storage sleeve 8... A storage compartment 801 containing bolts is aligned with the inlet / outlet hole 601. The pressure plate 10 presses the corresponding bolts into the channel 401. Then, the electric screwdriver works, and the screw of the electric screwdriver extends forward, pushing the bolt in the channel 401 into the through rod 5. Finally, the screw of the electric screwdriver pushes the bolt out from the through rod 5 and screws it into the hole. Through the continuous rotation of the storage sleeve 8, the storage compartment 801 containing bolts is aligned with the inlet / outlet hole 601 in sequence, so that the bolts can be quickly replenished into the channel 401.

[0047] In addition, a bolt positioning element is provided at the front end of the through rod 5. After the bolt is pushed to the front end of the through rod 5 by the screw of the electric screwdriver, the positioning element can position the bolt. That is, the threaded end of the bolt protrudes, and the head of the bolt is clamped by the clamping block of the positioning element. At this time, align the threaded end of the bolt with the hole, and press the screw of the electric screwdriver again. The clamping block of the positioning element opens to both sides, thereby allowing the bolt to pass through and completing the installation of the bolt.

[0048] likeFigures 3-7 As shown, during the sliding process of the inner sleeve 2, in order to automatically drive the storage sleeve 8 to rotate, specifically, the outer sleeve 1 has a double sleeve structure and forms a sandwich, the inner sleeve 2 slides in the middle of the outer sleeve 1, and a rotating cylinder 11 rotates inside the sandwich. The rotating cylinder 11 is connected to the storage sleeve 8. Vertical grooves 1101 are formed in a circular array on the inner wall of the rotating cylinder 11. An inclined groove 1102 is provided between two adjacent vertical grooves 1101, and the two ends of the inclined groove 1102 are respectively connected to the upper and lower ends of the two vertical grooves 1101, forming a wave structure with connected ends. A sliding column 12 is fixed on the side wall of the inner sleeve 2. The end of the sliding column 12 away from the inner sleeve 2 is slidably connected to the vertical groove 1101 and the inclined groove 1102.

[0049] When the inner sleeve 2 slides downward, the sliding column 12 slides along the vertical groove 1101. At this time, during the downward sliding process of the inner sleeve 2, the sliding column 12 will not cause the rotating drum 11 to rotate.

[0050] When the inner sleeve 2 slides upward, the sliding column 12 slides along the inclined groove 1102. At this time, during the upward sliding of the inner sleeve 2, the sliding column 12 and the inclined groove 1102 cooperate to drive the rotating cylinder 11 to rotate. At this time, the rotating cylinder 11 carries the storage sleeve 8 to rotate automatically, so that the other storage compartment 801 rotates to the state of being aligned with the inlet / outlet hole 601.

[0051] The sliding column 12 is slidably connected to a telescopic head 14 via a third spring 13. The end of the telescopic head 14 slides on the bottom of the vertical groove 1101 and the inclined groove 1102. The bottom of both the vertical groove 1101 and the inclined groove 1102 are inclined. The lower bottom of the vertical groove 1101 is higher than the lower bottom of the inclined groove 1102 in the form of a cliff, and the lower bottom of the vertical groove 1101 is lower than the lower bottom of the inclined groove 1102 in the form of a cliff.

[0052] The cliff face is characterized by a stepped section at both the upper and lower ends of both the vertical groove 1101 and the inclined groove 1102.

[0053] When the sliding column 12 slides downward along the vertical groove 1101 (as shown in the image) Figure 7 As shown, sliding in the direction of the solid arrow), due to the inclined bottom of the vertical groove 1101, the telescopic head 14 slides on the bottom of the vertical groove 1101 and is continuously pressed into the sliding column 12 by the bottom of the vertical groove 1101, that is, the third spring 13 is continuously compressed. When the sliding column 12 slides to the step position at the lower end of the vertical groove 1101, the telescopic head 14 will be popped out by the third spring 13. At this time, with the cooperation of the telescopic head 14 and the step setting, when the sliding column 12 slides upward, the sliding column 12 will slide along the inclined groove 1102 (as shown). Figure 7As shown, sliding along the direction of the hollow arrow, since the sliding column 12 slides axially relative to the outer sleeve 1 when it slides upward, the rotating cylinder 11 and the storage sleeve 8 will rotate circumferentially relative to the outer sleeve 1. After the sliding column 12 slides to the upper end of the inclined groove 1102, the sliding column 12 will be limited to the upper end of the next vertical groove 1101 by using the telescopic head 14 and the step at the upper end of the inclined groove 1102. When the inner sleeve 2 slides downward again, the sliding column 12 will slide downward in another vertical groove 1101. The sliding of the inner sleeve 2 is repeated in sequence to realize the automatic driving of the rotation of the storage sleeve 8.

[0054] like Figure 3 As shown, when the ring 6 is fixed on the fixed plate 4, in order to connect the storage sleeve 8 with the rotating cylinder 11 and make the storage sleeve 8 and the rotating cylinder 11 rotate synchronously, specifically, the upper end of the storage sleeve 8 is fixed with a plug post 19, and the side wall of the rotating cylinder 11 is provided with a plug hole 20 for the plug post 19 to be inserted. When the ring 6 is fixed on the fixed plate 4, the plug post 19 is inserted into the inside of the plug hole 20. With the cooperation of the plug post 19 and the plug hole 20, the rotation of the rotating cylinder 11 can drive the rotation of the storage sleeve 8.

[0055] like Figures 2-5 As shown in Figures 8 and 11, in order to prevent the bolts in channel 401 from slipping into the outer sleeve 1, specifically, a blocking member 21 is fixed at the middle of the lower end face of the outer sleeve 1. The blocking member 21 includes a fixing ring 2101, which is composed of two ring discs joined together. Inside the fixing ring 2101, two blocks 2103 are symmetrically slidably connected by a fifth spring 2102 to block the inner hole of the fixing ring 2101. The upper end connection of the two blocks 2103 is provided with a supporting wall 2104 for the screw of the electric screwdriver to be opened. When the screw of the electric screwdriver moves downwards... When the screw of the electric screwdriver is in operation, the end of the screw will push against the support wall 2104, causing the two stops 2103 to compress the fifth spring 2102 and move to both sides to open. At this time, the screw of the electric screwdriver can pass through the inner hole of the fixing ring 2101, so that the screw of the electric screwdriver can reach the channel 401. Conversely, when the screw of the electric screwdriver slides upward and is pulled out from the inner hole of the fixing ring 2101, the fifth spring 2102 presses the two stops 2103, causing the two stops 2103 to block the inner hole of the fixing ring 2101 again, effectively preventing the bolt in the channel 401 from entering the outer sleeve 1.

[0056] Example 3

[0057] like Figure 13 , Figure 14As shown, based on Embodiment 1, this embodiment aims to collect bolts removed by an electric screwdriver. Specifically, the collection component includes a collection bag 22, which is fixed to a ring 6. The opening of the collection bag 22 is aligned with the inlet / outlet hole 601. After the ring 6 is fixed to the fixing plate 4, the opening of the collection bag 22 communicates with the channel 401 through the inlet / outlet hole 601. When the screw of the electric screwdriver passes through the through rod 5 to remove the bolt, the screw of the electric screwdriver magnetically attracts the bolt. When the bolt is reset upwards, the screw of the electric screwdriver pulls the bolt from the through rod 5 into the channel 401. At this time, the opening of the channel 401 is placed downwards, that is, the collection bag 22 is located below the ring 6. The bolt will automatically fall into the collection bag 22 from the channel 401, thus collecting the bolt.

[0058] According to the descriptions of Embodiments 2 and 3, two rings 6 need to be configured. One ring 6 is provided with a storage sleeve 8, and the other ring 6 is provided with a storage bag 22. When bolts need to be installed, the ring 6 with the storage sleeve 8 is installed on the fixed plate 4 to improve the convenience of bolt installation. The ring 6 with the storage bag 22 is installed on the fixed plate 4 to improve the convenience of bolt disassembly.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
