The present invention relates to a pair of hairdressing scissors and the connecting device thereof, and more particularly to a pair of hairdressing scissors having connecting device formed on the handle portion thereof, so that plural pairs of such hairdressing scissors can be detachably secured to one another.

2. Description of the Prior Arts

A hairstylist cuts a customer's hair with several techniques, including trimming, thinning, layering, etc. Sometimes the hairstylist has to hold plural pairs of scissors in the same hand for proceeding with the thinning or layering of the hair to obtain the desired special hairstyle.
During operation of the plural pairs of scissors in the same hand, the user must keep the plural pairs of scissors be spaced at regular intervals and operate them with the same operating condition. The plural pairs of scissors must open and close synchronously to obtain a tidy, beautiful hairstyle. However, the plural pairs of scissors are simply held by fingers of the user such that the plural pairs of scissors cannot be operated synchronously due to touchy control of the plural pairs of scissors by the fingers. Thus, the plural pairs of scissors often become skew to one another and the spacing therebetween may be different from one another. The haircutting result is adversely affected, and this problem is aggravated if the user is inexperienced. The user often feels pain when operating the plural pairs of scissors in addition to numerous limitations to and difficulties in operation.
