Referring to fig. 1 and 2, an embodiment of the present invention provides a high pressure oil injection nozzle, which comprises an oil pipe 1, a movable sleeve, a sleeve 2 arranged outside the oil pipe 1, and a connecting pipe 3 arranged on one side of the oil pipe 1. The connecting pipe 3 can be used for connecting an oil inlet pipe. One end of the oil pipe 1 close to the oil outlet is integrally connected with a plurality of clamping pieces 11, the clamping pieces 11 are circumferentially and uniformly distributed on the oil pipe 1, and a gap is formed between every two adjacent clamping pieces 11. The clamping pieces 11 are preferably 6 pieces, the deformation amount is larger, and the clamping is more convenient. The clamping piece 11 radially expands along the direction of keeping away from the connecting pipe 3, reduces the distance of clamping

piece

11 and 1 internal diameter of oil pipe, and in the time of the oil feed, the deformation volume is little, prevents to connect because of the high pressure drops. The sleeve 2 is used for connecting the joint when moving downwards to expose the clamping piece 11, and after the joint is connected, the sleeve 2 moves upwards to cover the clamping piece 11, so that the joint is not easy to loosen from the clamping piece 11.

Referring to fig. 1, in an alternative embodiment, a rubber oil inlet pipe 12 and a metal pipe 13 sleeved outside the rubber oil inlet pipe 12 are disposed in an oil pipe 1, and a small through hole 121 is axially formed in the rubber oil inlet pipe 12. The small through hole 121 has a smaller diameter than the inner diameter of the oil pipe 12, and can increase the oil discharge pressure.

One end of the inner spring 5 is clamped into the mounting groove 122, and the other end of the inner spring is clamped into the clamping groove of the connecting pipe 3, so that the inner spring 5 is prevented from shaking in disorder. Because the inner spring 5 is longer, the spring with the large middle and the small two sides is adopted, the deformation of the spring in the oil inlet process is prevented, and the rubber oil inlet pipe 12 retreats to influence the oil outlet effect.

Referring to fig. 2, in an alternative embodiment, a small blocking piece 111 is formed at one end of the clamping piece 11 away from the connecting pipe 3 in an axially extending manner, the small blocking piece 111 extends in a direction close to the connecting pipe 3, and an opening smaller than the inner hole of the oil pipe 1 is formed between the small blocking pieces 111. The connector is clamped by the small blocking piece 111, so that the clamping effect is better.

Referring to fig. 3, in an alternative embodiment, a clamping shoulder 14 is provided on the outside of the oil pipe 1, and when the sleeve 2 abuts against the clamping shoulder 14, the sleeve 2 covers the side surface of the clamping piece 11. The casing 2 is supported by the clamping shoulder 14 when being sleeved on the highest point of the oil pipe 1.

Referring to fig. 1 and 3, in an alternative embodiment, a first handle 21 is symmetrically disposed at both sides of the sleeve 2, and the first handle 21 is provided with a first recess 22 at a side adjacent to the holding piece 11. An outer spring 4 is arranged between the sleeve 2 and the connecting pipe 3, and the outer spring 4 is sleeved on the oil pipe 1. The connecting pipe 3 is provided with a second handle 31, and the second handle 31 is provided with a second concave groove 32 at the side far away from the sleeve 2. The outer spring 4 initially brings the cannula 2 at its highest point against the catch shoulder 14. When the first handle 21 is pulled towards the second handle 31 and the sleeve 2 slides downwards to expose the clamping piece 11, the joint is clamped into the small blocking piece 111, the first handle 21 is released, and the sleeve 2 is jacked upwards by the outer spring 4 to cover the clamping piece 11

Referring to fig. 3, in an alternative embodiment, the side of the connection tube 3 away from the sleeve 2 is provided with an internally threaded hole 33, and flat openings 34 are symmetrically formed on the connection tube 3. The internal thread hole 33 can be used for connecting an oil inlet pipe, and the flat opening 34 is convenient for clamping a pipe wrench and is used for fixing the connecting pipe 3 on the oil pipe 1.
