The prior art drive unit 4, for example a cylinder or an assembly of an electric push rod, usually has only a degree of freedom in one direction, which is defined as the first direction. When the driving end of the driving unit 4 receives a force in the first direction, the driving unit 4 can counteract the external force by its own power or displacement of the driving end, without damaging the driving unit 4. However, when the driving end of the driving unit 4 is subjected to an external force in a direction other than the first direction, the driving end is pressed against other parts of the driving unit 4, so that the driving unit 4 is damaged. In order to solve the above-mentioned problems, the present application proposes a timepiece clamping device in which the driving unit 4 of the timepiece clamping device is often subjected to an external force in a direction other than the first direction.

Referring to fig. 1, in an embodiment of the present utility model, a meter body clamping device is provided, including a supporting frame 1, a driving unit 4, clamping members 3 and a sliding member 2, wherein the supporting frame 1 has a working surface for placing a meter body 7, the driving unit 4 is disposed on the supporting frame 1, the driving unit 4 has two driving portions that move back and forth along a first direction, the number of the clamping members 3 and the number of the sliding members 2 are consistent with the number of the driving portions, the clamping members 3, the sliding members 2 and the driving portions are in one-to-one correspondence, the corresponding clamping members 3 are connected with the driving portions through the sliding members 2, at least a portion of the clamping members 3 is located above the working surface, the two clamping members 3 are used for mutually cooperating to clamp the meter body 7 along the first direction, the sliding member 2 has a force transmission portion that can transmit torsion force received by the clamping members 3 to the supporting frame 1 along a second direction, the force transmission portion is movably contacted with the supporting frame 1, and the second direction is disposed at an included angle with the first direction.

Specifically, the support frame 1 is a component with a supporting function, and the support frame 1 is provided with a working surface, which can be arranged at the top of the support frame 1 or at other places of the support frame 1. And the sliding parts 2 are parts with a certain volume, and the two sliding parts 2 are arranged on the support frame body 1 in a sliding manner and are respectively connected with the two driving ends of the driving unit 4, and the two sliding parts 2 can be mutually far away from or close to each other under the action of the driving unit 4, so that the clamping parts 3 arranged on the sliding parts 2 are driven to be mutually far away from or close to each other. The force transmission part is a part of the slide 2, which is generally rigid and can conduct torsion. When the two clamping pieces 3 are driven by the driving unit 4 to be far away from each other, the watch body 7 can be loosened, and when the two clamping pieces 3 are driven by the driving unit 4 to be close to each other, the watch body 7 is clamped and fixed through the clamping pieces 3, and meanwhile, the position of the watch body 7 can be fixed.

According to the watch body clamping device provided by the embodiment of the utility model, when the watch body 7 is clamped, the driving unit 4 drives the two sliding parts 2 to be far away from or close to each other along the first direction, and simultaneously drives the clamping parts 3 arranged on the two sliding parts 2 to be far away from or close to each other, so that the clamping or loosening of the clamping parts 3 to the watch body 7 is realized, and the position accuracy and the fixation firmness of the watch body 7 can be ensured. Compared with the clamping device in the prior art, the clamping piece 3 is connected with the sliding piece 2, the sliding piece 2 is provided with the force transmission part which can transmit the torsion force received by the clamping piece 3 to the supporting frame body 1 along the second direction, and the second direction is arranged at an included angle with the first direction. After the watch body 7 is clamped by the clamping piece 3 under the action of the driving unit 4, and when the bottom cover is installed and needs to bear larger torsion, the torsion born by the watch body 7 can be transmitted to the sliding piece 2 by the clamping piece 3, the sliding piece 2 is provided with a force transmission part which can transmit the torsion born by the clamping piece 3 to the supporting frame body 1 along the second direction, the sliding piece 2 can transmit the torsion to the whole supporting frame body 1 along the second direction, and the torsion along the second direction is counteracted by the supporting frame body 1, so that the torsion along the second direction is prevented from being transmitted to the driving unit 4. Because the driving part on the driving unit 4 only has the freedom degree of moving along the first direction, the torque force along the second direction is transmitted to the driving unit 4 through the counteracting part of the supporting frame body 1, the risk of damage to the driving unit 4 caused by the torque force can be reduced to a certain extent, the power part 41 of the driving unit 4 is effectively protected, and the service life of the meter body clamping device is prolonged.

Specifically, the holding portion 31 and the main body portion 32 each refer to a member having a certain volume, and the holding portion 31 is provided at an end of the main body portion 32 near the watch body 7, and can be brought into contact with the watch body 7 through the holding portion 31 when the holder 3 approaches the watch body 7. The clip 3 is divided into two separate parts, a main body part 32 and a clip part 31. The clamping portion 31 can be made of a material with higher hardness, such as a piece of hard wear-resistant material like steel or bakelite, so that the wear of the clamping portion 31 is avoided and the service life of the clamping portion 31 is prolonged. The main body 32 is made of common materials, so that the overall manufacturing cost of the clamping piece 3 can be saved.

And clamping part 31 is dismantled with main part 32 and is connected, and the mode of dismantling the connection can make the grafting fixed, for example is provided with the grafting groove at clamping part 3 tip, is provided with the grafting portion with grafting groove complex on clamping part 31, can realize that only changing clamping part 31 and not changing whole clamping part 3 according to the model of table body 7. In addition, a clamping structure which is mutually matched with the watch body 7 can be arranged on the clamping part 31, for example, two positioning surfaces which are mutually arranged at intervals along the second direction are arranged on the clamping part 31, when the clamping part 31 is close to the watch body 7 along the first direction, the two positioning surfaces respectively abut against the inner sides of two watch ears to realize the positioning of the watch body 7 so as to prevent the watch body 7 from moving along the second direction, and a positioning groove which is arc-shaped and has an arc shape matched with the watch body 7 can be arranged on the clamping part 31, so that the contact area between the clamping part 31 and the watch body 7 can be increased when the clamping part 31 is contacted with the watch body 7, and the clamping and fixing of the watch body 7 are firmer. It should be understood, of course, that the positioning surface and the positioning groove may be present at the clamping portion 31 at the same time, so as to improve the clamping firmness of the watch body 7.

The foregoing description of the preferred embodiments of the utility model has been presented only to illustrate the principles of the utility model and not to limit its scope in any way. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model, and other embodiments of the present utility model as will occur to those skilled in the art without the exercise of inventive faculty, are intended to be included within the scope of the present utility model.
