[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] For example, see Figures 1 to 3 The present embodiment provides a screw machine pan-tilt stand, comprising a base 1, a handle 2 is fixed to one side of the top surface of the base 1, and a column 3 is fixed to the middle of the top surface of the base 1 away from the handle 2, a first lever 4 is rotatably mounted on the top of the column 3 through a damping shaft pin, and a second lever 5 is rotatably mounted on one end of the first lever 4 away from the column 3 through a damping shaft pin; A connecting plate 6 is fixed to one end of the second arm 5 away from the first arm 4, and the connecting plate 6 is arranged longitudinally. A mounting seat 7 is slidably mounted on the side of the connecting plate 6 away from the second arm 5. A screw machine 14 is inserted into the mounting seat 7. A plurality of positioning grooves 8 are formed on the inner wall of the mounting seat 7 at equal angles. A plurality of positioning strips 9 are formed on the outer wall of the lower end of the screw machine 14 at equal angles. The positioning strips 9 are inserted into the positioning grooves 8. The upper end of the positioning grooves 8 is an inverted funnel-shaped opening. The first force arm 4, the second force arm 5 and the base 1 can support the screw machine 14 at a working height, so that during the screwing process, it is not necessary to manually hold the screw machine 14 with one hand to bear the weight of the screw machine 14. When the screw machine 14 is inserted into the mounting seat 7, the positioning bar 9 and the positioning groove 8 can prevent the screw machine 14 from rotating. The opening shape of the upper end of the positioning groove 8 can make it easier to insert the positioning bar 9 into the positioning groove 8, thereby improving the assembly efficiency. A first sleeve 10 is fixed to the outer wall of the upper end of the mounting seat 7, and a first positioning pin 11 is slidably inserted at the axis of the first sleeve 10, and both ends of the first positioning pin 11 extend from the two ends of the first sleeve 10 respectively, and the first positioning pin 11 is located inside the first sleeve 10 and is close to the mounting seat 7. One end of the mounting seat 7 is formed with a first tightening ring 12, and the first positioning pin 11 is located on the inner side of the first sleeve 10. The outer side of the end of the mounting seat 7 away from the mounting seat 7 is sleeved with a first spring 13, one end of the first spring 13 is squeezed and contacted with the outer wall of the first tightening ring 12, and the other end of the first spring 13 is squeezed and contacted with the inner wall of the first sleeve 10, and the end of the first positioning pin 11 close to the mounting seat 7 is slidably connected with the mounting seat 7 through the sliding hole, and the end of the first positioning pin 11 close to the mounting seat 7 passes through the mounting seat 7 and extends to the inner side of the mounting seat 7 and is clamped on the horizontal edge 1401 at the lower end of the screw machine 14, and the top surface of the end of the first positioning pin 11 close to the screw machine 14 is inclined; During the process of inserting the lower part of the screw machine 14 into the mounting seat 7, the lower part of the screw machine 14 can contact the inclined surface of the top surface of the first positioning pin 11, causing the first positioning pin 11 to slide and avoid until the screw machine 14 is fully inserted and then loses the contact. Under the action of the rebound force of the first spring 13, the first tightening ring 12 is pushed, thereby pushing the first positioning pin 11 to slide and engage on the horizontal edge 1401 at the lower end of the screw machine 14, positioning the screw machine 14 in the mounting seat 7, and preventing the screw machine 14 from deviating during the process of screwing. When disassembling the screw machine 14, the first positioning pin 11 is released from the engagement by pulling one end of the first positioning pin 11 away from its inclined surface, so that the screw machine 14 can be removed. A lifting frame 15 is slidably installed on the side of the connecting plate 6 close to the mounting seat 7, a sliding bar 16 is symmetrically fixed on the side of the lifting frame 15 close to the connecting plate 6, a sliding rail 17 is symmetrically fixed on the side of the connecting plate 6 close to the lifting frame 15, and the two sliding bars 16 are respectively slidably connected to the outer walls of the two sliding rails 17, the mounting seat 7 is fixed to the side of the lifting frame 15 away from the connecting plate 6, a connecting bow 33 is fixed on the upper end of the connecting plate 6, a second spring 18 is connected between the upper end of the connecting bow 33 and the upper end of the lifting frame 15, a rotating rod 19 is rotatably connected to the side of the lifting frame 15 away from the connecting plate 6 through a bearing, a first gear 20 is fixed on one end of the rotating rod 19, a first rack 21 is fixed on the side of the connecting plate 6 close to the first gear 20, the first gear 20 is meshed with the first rack 21, and a turning handle 22 is also fixed on the end of the rotating rod 19 close to the first gear 20; The worker pulls the screw machine 14 so that the drill bit of the screw machine 14 is directly above the bolt that needs to be turned, and then turns the handle 22 to drive the rotating shaft 27 to rotate, so that the first gear 20 rotates and drives the first rack 21, so that the lifting frame 15 overcomes the elastic force of the second spring 18 and slides downward, so that the drill bit of the screw machine 14 descends and is inserted into the bolt to perform the screw driving work. After the screw driving is completed, the drill handle is loosened, and the lifting frame 15 is pulled up and reset under the action of the rebound force of the second spring 18. Compared with the traditional screw driving process, the weight of the entire screw machine 14 and the lifting and lowering of the screw machine 14 are all borne manually. The structural design of the present invention greatly reduces the labor intensity of the workers and improves the production efficiency.

In the process of transporting and storing the entire device, the positioning rod 23 and the lifting sleeve 24 can effectively limit the position of the screw machine 14, the first force arm 4 and the second force arm 5, avoiding arbitrary rotation and deviation during movement and transportation.
