The punching mechanism is arranged inside one end of the base, and the adjustment mechanism is arranged inside the other end of the base. When the hole puller is in use, the flow of hydraulic oil inside the equipment is realized by swinging the movable handle, pushing the piston in the hydraulic cylinder to move, driving the extrusion male die to move and push part of the workpiece into the female die to realize the punching of the workpiece surface. The adjustment mechanism includes a threaded rod, and a scale is provided on the threaded rod. The position of the punching can be adjusted by adjusting the threaded rod;

[0004] When the hole puller needs to be moved, the manual hydraulic pump hydraulically drives the mold driver through the high-pressure flexible connecting pipe, and the hole punching mold is installed on the workpiece that needs to be punched to achieve the purpose of punching holes on the workpiece. However, installing the hole punching mold on the workpiece will damage the surface of the workpiece. Since there is no positioning device, accurate drilling will not be possible if it is not installed and fixed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 , a movable hole puller with positioning function, comprising a punching mechanism for drilling a hole in a workpiece;

[0022] The punching mechanism comprises a body 2 and a punching head 1 fixed to the output end of the body 2;

[0023] The machine body 2 is held, and the punching head 1 is aligned with the position of the workpiece to be drilled, and then the machine body 2 is opened, so that the punching head 1 drills a hole on the workpiece, thereby achieving a hole-drilling effect.

[0024] However, in practice, during the drilling process, the drilling mechanism and the workpiece of the drilling head 1 lack positioning settings, so that a person needs to manually press the workpiece for a long time while holding the body 2 for a long time;

[0025] Further, refer to Figure 1 As shown, it is worth noting that it also includes a clamping mechanism for ensuring the stability of the workpiece during the drilling process;

[0026] The clamping mechanism includes a shell 3 which is a rectangular parallelepiped as a whole, a C-shaped groove is opened at one end of the shell 3, the body 2 is located in the C-shaped groove, and a hydraulic mechanism 5 is arranged between the body 2 and the innermost inner wall of the C-shaped groove, the telescopic end of the hydraulic mechanism 5 is fixedly connected to the body 2, and handles 7 are fixed at both upper and lower ends of the shell 3;

[0027] By setting the clamping mechanism, the two handles of the shell 3 are convenient to hold and can maintain stability during use. The front end of the shell 3 is two upper and lower planes. The front end of the shell 3 can be attached to the workpiece to play a fixing role, so that the workpiece does not need additional fixation. The hole puller is started, and the hydraulic mechanism 5 pushes the body 2 forward to complete the drilling, so that the drilling process can maintain a uniform and controllable speed, the workpiece will not be offset, and the workpiece can be well fixed.

[0028] Further, refer to Figure 1-3 As shown, it is worth noting that a slideway 4 is provided on the inner wall of the upper and lower ends of the inner groove of the housing 3, a positioning block 13 adapted to the slideway 4 is fixed on the outer wall of the hydraulic mechanism 5, and a fixing rod 8 is threadedly penetrated at both the upper and lower ends of the housing 3, and a mounting hole matching the fixing rod 8 is provided on the positioning block 13;

[0029] Through the arrangement of the slide 4 and the positioning block 13, when the hydraulic mechanism 5 is assembled into the C-shaped groove, the positioning block 13 can be simultaneously aligned and inserted into the slide 4, so that the positioning block 13 and the slide 4 cooperate to achieve the positioning effect of the hydraulic mechanism 5, so that the hydraulic mechanism 5, the body 2 and the punching head 1 are in a horizontal state as a whole, and then the knob fixing rod 8 is turned, so that the fixing rod 8 is inserted into the mounting hole on the positioning block 13 under the threaded structure, so that the hydraulic mechanism 5 can be tightened to prevent the hydraulic mechanism 5 from falling off from the C-shaped groove during the punching operation, affecting the use effect.

[0030] Further, refer to Figure 1 As shown, it is worth noting that a level ruler 6 is also provided on the upper side and the right side of the housing 3;

[0031] The level ruler 6 can detect whether the machine is level in the horizontal and vertical directions when in use, to prevent the punching mechanism from being improperly installed, resulting in deviation of the punching.

[0032] However, due to the different sizes of workpieces, once the length of the workpiece is smaller than the distance between the contact surfaces on both sides of the front end of the housing 3, the two sides cannot contact the workpiece at the same time;

[0033] Further, refer to Figure 1-2 As shown, it is worth noting that it also includes a retracting mechanism for enhancing the applicable scope of the clamping mechanism;

[0034] The retracting mechanism comprises two extension blocks 9 which are detachably arranged on the inner walls at both ends of the C-shaped groove, and the two extension blocks 9 are fixed with isosceles trapezoidal sliders at the opposite ends thereof, and the inner wall of the C-shaped groove is provided with a slide groove which matches with the sliders;

[0035] By setting the retracting mechanism, the slider on the extension block 9 is inserted into the slide groove, and the extension block 9 can reduce the inner diameter of the C-shaped groove, so that the shell 3 can press a smaller workpiece, thereby improving the application range of the shell 3.

[0036] Further, refer to Figure 2As shown, it is worth noting that screw rods 12 are vertically rotatably provided on both ends of the housing 3, a pressing block 11 is threadedly connected to the rod body of the screw rod 12, and positioning rods 10 are vertically fixed to both ends of the pressing block 11, and a fixing hole is opened on the slider, and the end of the positioning rod 10 penetrates into the slide groove and extends into the fixing hole;

[0037] After the extension block 9 is assembled into the C-shaped groove by using the slider and the slide groove, the knob screw 12 is then turned to cause the pressure block 11 to slide on the rod body of the screw 12 under the threaded structure, so that the positioning rod 10 can be inserted into the fixing hole to achieve the tightening effect of the extension block 9 and ensure the stability of the extension block 9 in the C-shaped groove.
