DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] For reference Figure 1-5 The utility model is described as follows:

[0031] A particle pusher convenient to use includes a long needle tube 1, the front end of the needle tube 1 is a needle tip, the rear end of the needle tube 1 is connected to a handle 2, the handle 2 is long and has a square cross section, and also includes a push cavity penetrating the needle tube 1 and the handle 2, and the particles move in the push cavity. It also includes a push rod 11, which can be inserted into the push cavity of the needle tube 1 and the handle 2 to push the particles.
