[0024] Please see Figure 1-6 and Figure 9 This embodiment describes a single-axis push-pull pull lever wrench, mounted on a machine base 2. The machine base 2 is inserted into a track 12 of a cabinet 1. The cabinet 1 has a mounting hole 11, which has a top wall 111 and a bottom wall 112 disposed opposite to each other. The single-axis push-pull pull lever wrench includes: Housing 3, which is fixed to the side of the machine base 2 facing the mounting hole 11 of the cabinet 1; The drive mechanism 4 includes a drive arm 41 and an assist arm 42. The movable ends of the drive arm 41 and the assist arm 42 are installed in the housing 3 and are connected in a transmission manner. The free end of the assist arm 41 is arranged in the direction of the mounting hole 11 so that when the free end of the drive arm 41 rotates, it drives the free end of the assist arm 42 to rotate in the same direction. The length of the drive arm 41 is greater than the length of the assist arm 42; The housing 3 and the mounting hole 11 have a preset distance, such that when the drive arm 41 drives the auxiliary arm 42 to rotate around the first direction, the free end of the auxiliary arm 42 abuts against the bottom wall 111 of the mounting hole 11, and the machine platform 2 slides into the cabinet 1; when the drive arm 41 drives the auxiliary arm 42 to rotate around the second direction opposite to the first direction, the free end of the auxiliary arm 42 abuts against the top wall 112 of the mounting hole 11, and the machine platform 2 slides out of the cabinet 1.

[0025] Based on the above structure, please refer to Figure 1-3This is a schematic diagram of the machine tool of a single-axis push-pull lever wrench provided in one embodiment. In the default state, at least part of the machine tool 2 and the housing 3 are positioned relative to each other on the outside of the cabinet 1. In the extreme state, the drive arm 41 is parallel to the paper in the up-down direction. The operator first pushes the drive arm 41 in the first direction, so that the free end of the drive arm 41 rotates clockwise around the paper. Simultaneously, the assist arm 42 also rotates clockwise under the transmission action. The free end of the assist arm 42 does not contact the mounting hole 11 at first, and then first abuts against the bottom wall 112 of the mounting hole 11, and applies a pushing force to the bottom wall 112. Since the cabinet 1 where the mounting hole 11 is located is fixed, the machine tool 2 slides relative to the cabinet 1 with the help of the track 12 until the free end of the assist arm 42 and the bottom wall 112 of the mounting hole 11 are in complete contact. The machine tool 2 then moves into position, achieving complete locking of the machine tool 2.

[0026] In contrast, please see Figure 4-6 This is a schematic diagram of the single-axis push-pull pull-out lever wrench in one embodiment, showing the machine's pulled-out state. In the default state, at least part of the machine base 2 and housing 3 are positioned relative to each other within the cabinet 1. In the extreme state, the drive arm 41 can be parallel to the left-right direction of the paper. The operator first pushes the drive arm 41 in the second direction, causing the free end of the drive arm 41 to rotate counterclockwise around the paper. Simultaneously, the assist arm 42 also rotates counterclockwise under the transmission action. The free end of the assist arm 42 initially aligns with the bottom wall 112 of the mounting hole 11. After contacting and then leaving the bottom wall 112 of the mounting hole 11, the machine 2 touches the top wall 111 of the mounting hole 11 again and applies a pushing force relative to the top wall 111. Since the cabinet 1 where the mounting hole 11 is located is fixed, the machine 2 slides relative to the cabinet 1 with the help of the track 12 until the free end of the assist arm 42 is completely separated from the top wall 111 of the mounting hole 11. The machine 2 then moves into position, realizing the initial pull-out of the machine 2. Then, the operator can pull the machine 2 further and completely pull it out as needed by pulling the drive arm 41.

[0027] Specifically, the aforementioned track 12 can be found in [reference needed]. Figure 7 It is a regular strip track that extends along the direction of movement of machine 2 and is set near the bottom of machine 2.

[0028] Based on the above technical solution of this utility model, the longer drive arm 41 can drive the auxiliary arm 42 to engage with the mounting hole 11 on the cabinet 1, thus assisting the operator in easily pulling the machine out of or pushing it into the cabinet 11. Specifically, in this utility model, the drive arm 41 is longer than the auxiliary arm 42. By utilizing the lever principle, the operator can push the drive arm 41 to drive the auxiliary arm 42 to rotate in the same direction, converting the operator's several kilograms of pushing force into tens of kilograms of pushing force at the end of the auxiliary arm 42, thereby propelling the heavier machine 2 relative to the cabinet 1. Furthermore, the structure is simple, easy to manufacture, and the mechanical transmission is stable.

[0029] The following are two embodiments involving different force transmission relationships in drive mechanism 4.

[0030] Example 1 In this embodiment, please refer to Figure 7 The drive mechanism 4 further includes a transmission gear 43, which is installed in the housing 3. The transmission gear 43 is positioned between the movable end of the drive arm 41 and the movable end of the assist arm 42. The movable end of the drive arm 41 is provided with a drive gear 44 that meshes with the transmission gear 43, and the movable end of the assist arm 42 is provided with an assist gear 45 that meshes with the transmission gear 43. The radius and number of teeth of the transmission gear 43, the drive gear 44, and the assist gear 45 are equal. Specifically, during operation, the drive arm 41 drives the drive gear 44 at its movable end to rotate, while the transmission gear 43 rotates in the opposite direction. Therefore, the assist gear 45 rotates in the opposite direction to the transmission gear 43 but in the same direction as the transmission gear 43, and the assist arm 42 rotates in the same direction as the drive arm 41. By setting the radius and number of teeth of the transmission gear 43, the drive gear 44, and the assist gear 45 to be equal, it is easy to save costs during the production stage and achieve the same rotation angle.

[0031] Example 2 In this embodiment, please refer to Figure 8The drive mechanism 4 includes a linkage between the movable end of the drive arm 41 and the movable end of the assist arm 42. Specifically, the drive mechanism 4 further includes a first transmission arm 46, a second transmission arm 47, and a third transmission arm 48. The first end of the first transmission arm 46 is fixedly connected to the movable end of the drive arm 41. The second end of the first transmission arm 46 is hinged to the first end of the second transmission arm 47. The second end of the second transmission arm 47 is hinged to the first end of the third transmission arm 48. The second end of the third transmission arm 48 is fixedly connected to the movable end of the assist arm 42. During operation, the movable end of the drive arm 41 rotates, causing it to exert a swaying force on the second end of the first transmission arm 46. Therefore, the first transmission arm 46 drives the second transmission arm 47 to perform an arc-shaped movement, which in turn causes the second transmission arm 47 to drive the third transmission arm 48 to perform an arc-shaped movement. Since the movable end of the assist arm 42 cannot move but can only rotate, the final result is that the third transmission arm 48 drives the fixed assist arm 42 to rotate, causing the free end of the assist arm 42 to perform an arc-shaped movement. The second transmission arm 47 in this application can be configured as a U-shaped design to avoid the movable end of the drive arm 41.

[0032] In the two embodiments described above, embodiment 1 of gear transmission has the advantages of stable and accurate transmission ratio, compact structure and small size, while embodiment 2 of linkage transmission has the characteristics of simple structure and low cost, and is especially suitable for use under low speed and high load conditions, and can be set as needed.

[0033] In another embodiment, please refer to Figure 9 The machine base is provided with a slot, and the free end of the drive arm is provided with a hook 5 that matches the slot. When the free end of the drive arm 41 rotates and is adjacent to the slot, the hook 5 can be hooked into the slot and lock the drive arm 41, just as... Figure 9 The state shown is such that, in the fully locked state, the drive arm 41 cannot move.

[0034] Specifically, see Figure 9 In fact, the machine platform 2 is equipped with a pair of single-axis push-pull pull bar wrenches arranged in a mirror image. In the case of a wide machine platform 2, the pair of single-axis push-pull pull bar wrenches are respectively arranged on the left and right sides of the machine platform 2, which facilitates the even pushing of the machine platform 2.

[0035] Further, please see Figure 1 , 2The housing 3 is square in shape and has a groove 31 for accommodating the assist arm 42. The assist arm 42 can be completely retracted into the groove 31 after rotating towards the housing 3. The square housing 3 can fit the machine base 2 and is easy to manufacture. After the assist arm 42 is completely retracted into the groove 31, its overall structure has minimal external interference.

[0036] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0037] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0038] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
