However, since the shape of the PE pipe is basically circular, the operator is required to continuously hold the PE pipe to ensure its stability during the opening operation, which increases the complexity and inconvenience of the operation. The continuous hand-holding action requires a lot of physical strength and may cause fatigue and discomfort to the operator during the operation, which is too time-consuming and laborious.

[0018] As a preferred embodiment, the inner surface of the second slide groove is slidably connected with a second slider, the second slider is movably sleeved on the outer surface of the screw, and a drilling device is fixedly installed on the bottom of the second slider.

[0019] The technical effect of adopting the above further solution is that the screw rod can drive the second sliding block to move left and right through the second sliding groove when rotating.

The outer surfaces of the two reverse screw rods 109 and the two forward-rotating screw rods 107 are movably sleeved with first sliding blocks 111, and the four first sliding blocks 111 are divided into two groups. The outer surfaces of the two groups of first sliding blocks 111 are slidably connected to the inner surface of the first sliding groove 110, and the tops of the two groups of first sliding blocks 111 are fixedly installed with clamping plates 112.

[0031] In this embodiment, the staff can first place the pipe in the middle of the clamping plate 112, and then start the motor 106 through the power supply system of the motor 106, so that when the motor 106 rotates, the second bevel gear 105 is driven to rotate through the second rotating rod 104 inside the flange 103, and then the second bevel gear 105 is transmitted to the first bevel gear 102, so that when the first bevel gear 102 rotates, the forward screw rod 107 is driven to rotate through the first rotating rod 101, and when the forward screw rod 107 rotates, it is transmitted to the reverse screw rod 109 through the third rotating rod 108, so that the forward screw rod 107 and the reverse screw rod 109 rotate synchronously. The first slide block 111 is driven by the first slide block 110 to perform relative translational motion, thereby causing the clamping plate 112 to move synchronously, so that the clamping plate 112 fits the outer surface of the pipe to clamp and fix the pipe, and then the drilling equipment 208 is started through the power supply system of the drilling equipment 208 to drill a hole in the pipe.

[0033] In this embodiment, after the pipe is fixed, the crank 206 can be rotated to transmit to the screw 204 inside the connecting plate 202 through the fourth rotating rod 205, so that the screw 204 drives the second slider 207 to move left and right through the second slide groove 203 when rotating, thereby driving the drilling device 208 to move synchronously, and adjusting the drilling position of the drilling device 208. After the position adjustment of the drilling device 208 is completed, the electric telescopic rod 201 can be started through the power supply system of the electric telescopic rod 201 inside the gantry 2, so that the electric telescopic rod 201 can be extended. When the drilling device 208 is lowered through the connecting plate 202, the pipe is drilled, and through structures such as the screw 204 and the second slider 207, drilling operations can be performed on different positions of the pipe, thereby improving the applicability of the device.

[0034] Working principle: When in use, the staff can first place the pipe in the middle of the clamping plate 112, and then start the motor 106 through the power supply system of the motor 106 (it should be noted that the motor 106 model is Y80M1-2, and the power is 0.75KW). When the motor 106 rotates again, the second rotating rod 104 inside the flange 103 drives the second bevel gear 105 to rotate, and then the second bevel gear 105 is transmitted to the first bevel gear 102, so that when the first bevel gear 102 rotates, the forward screw rod 107 is driven to rotate through the first rotating rod 101, and when the forward screw rod 107 rotates, it is transmitted to the reverse screw rod 109 through the third rotating rod 108, so that The forward-rotating screw rod 107 and the reverse-rotating screw rod 109 rotate synchronously, and then drive the first slider 111 to perform relative translational motion through the first slide groove 110, so that the clamping plate 112 moves synchronously, so that the clamping plate 112 fits the outer surface of the pipe to clamp and fix the pipe, and the drilling equipment is started through the power supply system of the drilling equipment 208 to drill a hole in the pipe. The linkage structure such as the motor 106 and the clamping plate 112 makes the device realize automatic clamping and positioning of the pipe when in use, without the operator having to hold the pipe continuously, which greatly reduces the labor intensity of the operator, improves work efficiency, and avoids instability and errors that may occur in hand-held operation. During use, after the pipe is fixed, the crank 206 can be turned to transmit the fourth rotating rod 205 to the screw 204 inside the connecting plate 202, so that the screw 204 drives the second slider 207 to move left and right through the second slide groove 203 when rotating, thereby driving the drilling device 208 to move synchronously, and adjusting the drilling position of the drilling device 208. After the position adjustment of the drilling device 208 is completed, the electric telescopic rod 201 can be started through the power supply system of the electric telescopic rod 201 inside the gantry 2, so that the electric telescopic rod 201 can be extended.
