Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 3, a clamping apparatus for improving production efficiency includes a housing 2. The housing 2 is cylindrical in shape, and has a mounting cavity 21 formed therein. The spiral disc 3 is rotatably connected in the mounting cavity 21 through a linkage mechanism 4.

The linkage mechanism 4 includes a driving rod 41, a gear 42, and a ring gear 43. The toothed ring 43 is fixed on one side of the spiral disc 3 back to the first clamping block 61 and is arranged coaxially with the spiral disc 3; the gear 42 is engaged with the toothed ring 43 and is fixedly connected to the drive rod 41. The driving rod 41 is rotatably connected to the housing 2 such that an end of the driving rod 41 remote from the gear 42 protrudes from the housing 2.

Four sliding grooves 5 are formed in the end portion of the mounting cavity 21, and the four sliding grooves 5 are evenly distributed along the axis of the spiral disc 3. Two first clamping blocks 61 and two second clamping blocks 62 are connected on the four sliding grooves 5 in a sliding manner; the two first clamping blocks 61 are arranged oppositely, and the two second clamping blocks 62 are arranged oppositely.

A sliding block (not shown in the figure) is fixed at one end of each of the first clamping block 61 and the second clamping block 62 close to the spiral disk 3; the slider is placed in a spiral groove on the spiral disk 3.
