Detailed description of the invention

With reference to accompanying drawing 1 to Fig. 4, a kind of measuring oil gun of the utility model is described in further details.

A kind of measuring oil gun, comprise handle 1, rifle body 2 and the electronic display unit 3 be placed on rifle body 2, oil outlet 21 place of described rifle body 2 is provided with gun barrel 4, described rifle body 2 is provided with the oil duct 23 being communicated with oil inlet 22 and oil outlet 21, the control cock 5 opened and closed for controlling oil duct 23 is provided with at oil duct 23, described control cock 5 comprises spring 51, open and close seat 52 and push rod 53, described keying seat 52 is provided with packing seal 54, described keying seat 52 is sealed and matched by packing seal 54 and oil duct 23, one end and the spring 51 of described keying seat 52 are inconsistent, the other end is connected with push rod 53, it is inconsistent with handle 1 that described push rod 53 passes rifle body 2, when pressing push rod 53 by handle 1, described push rod 53 drives keying seat 52 to move and opens oil duct 23, described keying seat 52 Compress Spring 51, when decontroling handle 1, open and close seat 52 to realize resetting at Compress Spring 51, close oil duct 23.
