[0025] In addition, the meaning of the term "a plurality of" should be two and more than two.

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0027] As Figs. 1-2As shown, a foot-operated center stretching device includes a workbench 1, a first sleeve 2, and a second sleeve 3, wherein the first sleeve 2 is fixedly arranged on the workbench 1, the second sleeve 3 is slidingly arranged on the workbench 1, the first sleeve 2 and the second sleeve 3 are oppositely arranged, and the ends of the first sleeve 2 and the second sleeve 3 opposite to each other are fixedly provided with a center body 4; further comprising a foot-operated jacking assembly fixedly arranged on the workbench 1, the input end of the foot-operated jacking assembly extends to the outside of the workbench 1, and the foot-operated jacking assembly drives the second sleeve 3 to slide along the axial direction.

[0028] Specifically, when the worker is ready to clamp the fixture containing the product by the magnetic device, if the product size is too large or the weight is too heavy, the worker can choose to hold the fixture with both hands, and then use a single foot to step on the foot-operated jacking assembly, so that the foot-operated jacking assembly drives the second sleeve 3 to move away from the first sleeve 2, and then the center bodies 4 on the first sleeve 2 and the second sleeve 3 move away from each other, and then the fixture can be placed between the two center bodies 4. The embodiment improves the original form of pulling the fixture with one hand with one hand to the form of holding the fixture with both hands, and controls the movement of the center bodies 4 by stepping on the foot-operated jacking assembly, which avoids the risk of fixture falling caused by single-handed fatigue during production, and still allows single-person operation, ensuring work efficiency.

[0029] The foot-operated jacking assembly includes a cylinder 5, an oil pipe 6, an extension rod 7, and an oil pump 8, the cylinder 5 is fixedly arranged in the workbench 1, one end of the oil pipe 6 is fixedly connected with the cylinder 5, the other end of the oil pipe 6 extends out of the workbench 1 and is fixedly connected with the oil pump 8, one end of the extension rod 7 is inserted into the cylinder 5, and the other end of the extension rod 7 is fixedly connected with the outer wall of the second sleeve 3 through a first connecting rod 9. Specifically, when the oil pump 8 is stepped on, hydraulic oil is pumped into the cylinder 5 through the oil pipe 6, the extension rod 7 in the cylinder 5 moves outward, and then drives the second sleeve 3 to slide axially, so that the two center bodies 4 move away from each other.

[0030] The end of the second sleeve 3 away from the first sleeve 2 is further fixedly provided with an elastic member 10 between the workbench 1. Specifically, when the fixture is placed in place, the oil pump 8 is loosened, the hydraulic oil in the cylinder 5 is discharged, and the elastic force of the elastic member 10 drives the second sleeve 3 to move towards the first sleeve 2. The function of the elastic member 10 here is to reset the clamping of the second sleeve 3, and the elastic member 10 can be selected from springs, elastic sheets, etc.

[0031] Further comprising a hand pulling assembly fixedly connected with the second sleeve 3, the hand pulling assembly is located on the upper side of the second sleeve 3. The hand pulling assembly comprises a hand pulling rod 11 and a second connecting rod 12, one end of the second connecting rod 12 is fixedly connected with the outer wall of the sleeve, and the other end is fixedly connected with one end of the hand pulling rod 11. Specifically, when fixing lighter products or smaller products, it may not be necessary to hold with both hands, at this time, single-handed holding of the product can still be carried out, and the other hand can pull the second sleeve 3 by means of the hand pulling rod 11 and the second connecting rod 12, thereby providing another operation mode for the user to pull open the second sleeve 3.

[0032] The workbench 1 is fixedly provided with a sliding seat 13, a sliding groove 14 is formed in the middle of the sliding seat 13, and the second sleeve 3 is slidingly arranged in the sliding groove 14. Specifically, the second sleeve 3 slides in the sliding groove 14, which can guide the movement direction of the second sleeve 3 and avoid deviation.

[0033] The workbench 1 is further fixedly provided with a transverse hand wheel 15 and a longitudinal hand wheel 16 for adjusting the horizontal position of the sliding seat 13. Specifically, different products or clamps may have different clamping positions when clamped, at this time, the horizontal position of the sliding seat 13 can be adjusted by the transverse hand wheel 15 and the longitudinal hand wheel 16 to meet the needs, it should be noted that how the transverse hand wheel 15 and the longitudinal hand wheel 16 adjust the position of the sliding seat 13 is not the core point of the present application, any structure that can realize the above adjustment function can be applied here.

[0034] The oil cylinder 5 is fixedly arranged in the inside of the sliding seat 13. Specifically, since the position of the sliding seat 13 is adjustable, the oil cylinder 5 is arranged on the sliding seat 13 as the second sleeve 3, so that the relative position between the second sleeve 3 and the oil cylinder 5 remains unchanged no matter how the sliding seat 13 moves, thereby the second sleeve 3 can always be controlled by stepping.

[0035] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
