DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The present application embodiment discloses a universal clamp. Figure 1 The universal clamp includes a grip rod 1 and a clamping jaw 2, wherein the grip rod 1 is a round rod, and for better strength, the grip rod 1 is preferably made of metal material such as stainless steel; two clamping jaws 2 are rotatably arranged at one end of the grip rod 1, and the two clamping jaws 2 are relatively bent, and a clamping area 3 for clamping an object is formed between the two clamping jaws 2.

[0033] Furthermore, a connecting seat 4 is fixed to one end of the gripping rod 1. The connecting seat 4 is trapezoidal in shape as a whole. A clearance groove 41 for the jaws 2 to pass through is provided at the end of the connecting seat 4 away from the gripping rod 1, thereby forming a flared opening. The rods of the two jaws 2 can move closer to or farther away from each other in the clearance groove 41. The universal clamp also includes a driving member 5 for driving the jaws 2 to rotate toward the clamping area 3. The driving member 5 is respectively arranged in a one-to-one correspondence with the two jaws 2; specifically, the driving member 5 includes a driving rod 51 and a power source 52. The driving rod 51 passes through the side wall of the connecting seat 4 and can abut against the side wall of the jaw 2 away from the holding area. Preferably, the driving rod 51 can be arranged perpendicular to the outer wall surface of the connecting seat 4, and the power source 52 can drive the driving rod 51 to move toward or away from the holding area.

[0034] Reference Figure 1 and Figure 2 In this embodiment, an external thread is provided on the outer side wall of the driving rod 51, and the driving rod 51 is threaded through the side wall of the connecting seat 4. The power source 52 is a motor, and preferably a micro motor. The output end of the motor is connected to the end of the driving rod 51 away from the clamping area 3; in order to install the motor, a positioning seat 6 is provided on the outer side wall of the connecting seat 4, and the positioning seat 6 includes a first plate 64 and a second plate 65 that are perpendicular to each other. The first plate 64 and the second plate 65 are in an "L" shape, wherein the first plate 64 is perpendicular to the surface of the side wall of the connecting seat 4, and the second plate 65 is parallel to and abuts against the side wall of the connecting seat 4. The motor is slidably installed on the side wall of the first plate 64, and the second plate 65 is detachably fixed to the positioning seat 6 by bolts or the like, so that the motor can be quickly installed and disassembled through the positioning seat 6.

[0035] Furthermore, a mounting plate 61 is slidably provided on the side wall of the first plate 64 facing away from the second plate 65, and the motor is fixed on the mounting plate 61. A guide block 62 is fixed on the side wall of the mounting plate 61 facing the first plate 64. The guide block 62 can be a T-block, a dovetail block, etc. A guide groove 63 for sliding the guide rod block is opened on the side wall of the first plate 64, and the guide groove 63 extends in a direction perpendicular to the side wall of the first plate 64; the installation of the motor is realized by the setting of the mounting plate 61, and the sliding guidance of the mounting plate 61 is realized by the cooperation of the guide block 62 and the guide groove 63, thereby improving the stability of the motor during movement.

[0036] Start the motor, and the motor drives the driving rod 51 to rotate. With the threaded connection between the driving rod 51 and the connecting seat 4, and the cooperation between the guide block 62 and the guide groove 63, the motor and the driving rod 51 can move together toward or away from the clamping area 3, so that the driving rod 51 can drive the clamping claw 2 to rotate toward the clamping area 3 to clamp the object, that is, the automatic clamping of the object can be realized, and the clamping method is convenient and fast.

[0037] Reference Figure 1 and Figure 2 Further optionally, a sliding groove 21 can be opened on the side wall of the two clamping jaws 2 facing away from each other, and the sliding groove 21 extends along the length direction of the clamping jaws 2. The end of the driving rod 51 facing away from the motor is preferably set to an arc-shaped ball head structure, so that the end of the driving rod 51 can slide in the sliding groove 21, and the ball head structure of the driving rod 51 can make it slide more smoothly.

[0038] Reference Figure 2 and Figure 3 A central axis is arranged on the connecting seat 4, and the central axis passes through one end of the two clamping jaws 2 away from the clamping area 3, and the two clamping jaws 2 can rotate around the central axis.

[0039] In an optional embodiment, a coil spring 42 is coaxially sleeved on the outer side of the central axis, and the two ends of the coil spring 42 are respectively fixed to the two clamping jaws 2. When the two clamping jaws 2 move away from each other until they abut against the side walls of the clearance groove 41, the coil spring 42 is in a compressed state, so that the coil spring 42 can provide elastic force for the two clamping jaws 2 to always rotate in a direction away from each other, so as to facilitate clamping of objects.

[0040] Reference Figure 2 and Figure 3 In an optional embodiment, a protective cover 7 can be further provided at one end of the clamping jaw 2 away from the gripping rod 1. The protective cover 7 is made of an elastic material such as silicone or rubber and is used to form a buffer, thereby preventing the clamping jaw 2 from directly contacting the object when clamping the object, thereby preventing the clamped object from being damaged. At the same time, the deformation of the protective cover 7 can increase the friction between the clamped object and the clamped object, thereby improving the stability of the clamping.

[0041] Furthermore, the protective sleeve 7 can be wound on the clamping jaw 2, and a fixing member 8 for fixing the two ends of the protective sleeve 7 on the clamping jaw 2 is provided on the side of the clamping jaw 2 away from the clamping area 3. The fixing member 8 can be a fixing bolt. When the protective sleeve 7 wraps around the clamping jaw 2, the two ends of the protective sleeve 7 can overlap each other and the side of the clamping jaw 2 away from the clamping area 3. The fixing bolt passes through the two ends of the protective sleeve 7 at one time and is threadedly connected to the side wall of the clamping jaw 2, thereby fixing the protective sleeve 7. This arrangement can facilitate the installation and removal of the protective sleeve 7, and can also prevent it from falling off during use, further improving the safety during use.

[0042] Further preferably, a pressure sensor may be provided on the side of the clamping jaw 2 facing the clamping area 3, and the pressure sensor is connected to the power source 52. Through the provision of the pressure sensor, the clamping force of the clamping jaw 2 on the object can be detected in real time, and the detected pressure value is transmitted to the power source 52, so that the power source 52 can adjust the output according to the actual situation, further improving the clamping effect and avoiding damage to the object due to excessive clamping force.

[0043] Optionally, a display screen may be provided on the side wall of the grip rod 1 for setting a reference pressure value and displaying the pressure value in real time, thereby facilitating the operator to control the universal clamp.

[0044] The implementation principle of a universal clamp in an embodiment of the present application is as follows: when in use, first pre-set the pressure value according to the object to be clamped, and then start the two power sources 52 at the same time, drive the two driving rods 51 to rotate and approach the clamping area 3, thereby driving the two clamping claws 2 to approach each other through abutment and clamp the object; when it is necessary to release the object, just start the power source 52 again to drive the two driving rods 51 to move away from the clamping area 3, and the two clamping claws 2 move away from each other under the action of the coil spring 42, open the clamping claws 2, and the clamped object can be released.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
