The first telescopic rod 4 is rotatably connected with the connecting plate 2 and the positioning plate 3, so that the angle of the drawbar can be adjusted, thereby facilitating use.

[0023] Example 2: Figures 1 to 4 As shown, a positioning clamping mechanism 6 is installed between the interior of the first telescopic rod 4 and the positioning plate 3, and the positioning clamping mechanism 6 includes a first spring 61 fixedly connected to the interior of the bottom end of the first telescopic rod 4, one end of the first spring 61 is fixedly connected to the second telescopic rod 62, and the outer surface of the bottom end of the second telescopic rod 62 is fixedly connected to a positioning rod 63, one end of the positioning rod 63 passes through the bottom end of the first telescopic rod 4 and extends to the outside, and the outer surface of the positioning plate 3 is annularly provided with a plurality of positioning holes 64 that match the positioning rod 63. When positioning the pull rod, the first spring 61 will automatically drive the second telescopic rod 62 and the positioning rod 63 to reset and make the positioning rod 63 enter the corresponding positioning hole 64, so as to quickly fix the pull rod angle, and the simple structure can reduce the production cost, thereby solving the problem that the existing pull rod positioning structure is complicated and increases the production cost.

[0024] Example 3: Figures 1 to 5 As shown, a driving mechanism 7 matched with the positioning clamping mechanism 6 is installed inside the handle 5, and the driving mechanism 7 includes a U-shaped groove 71 opened inside the handle 5, and a mounting groove 72 is opened at the top of the U-shaped groove 71. A first wedge plate 73 and a second wedge plate 74 are symmetrically slidably connected inside the U-shaped groove 71, and one end of the first wedge plate 73 and the second wedge plate 74 are respectively fixedly connected to the top of the corresponding second telescopic rod 62, and a wedge block 75 matched with the first wedge plate 73 and the second wedge plate 74 is embedded and slidably connected inside the mounting groove 72.

When unlocking the pull rod positioning, it is only necessary to press the wedge block 75 downwards to drive the first wedge plates 73 and the second wedge plates 74 on both sides to move relatively apart, thereby driving the second telescopic rods 62 on both sides to move relatively apart, so that the positioning rods 63 on both sides can be moved out of the positioning holes 64 at the same time, thereby unlocking the pull rod. The convenient operation can reduce the workload, thereby solving the problem of increasing the workload by pushing and pulling the push rods on both sides at the same time when adjusting the existing pull rod.

[0027] Working principle: When unlocking the pull rod positioning, it is only necessary to press the wedge block 75 downwards to drive the first wedge plate 73 and the second wedge plate 74 on both sides to move relatively away from each other, and then the second telescopic rod 62 on both sides can be driven relatively away from each other, so that the positioning rods 63 on both sides can be moved out of the positioning holes 64 at the same time, and the lock of the pull rod can be released. The convenient operation can reduce the workload, thereby solving the problem of the existing pull rod adjustment that requires pushing and pulling the push rods on both sides at the same time and increasing the workload. When positioning the pull rod, the first spring 61 will automatically drive the second telescopic rod 62 and the positioning rod 63 to reset and make the positioning rod 63 enter the corresponding positioning hole 64, so as to quickly fix the pull rod angle. The simple structure can reduce the production cost, thereby solving the problem of the existing pull rod positioning structure being complicated and increasing the production cost.
